Writing a book is easy. You sit down by the keyboard, slit your wrists, and pour your self out. (That's not a typo, btw.) I've written one, and in the process acquired a near limitless admiration for those who can do it for living, book after book, decade after another. Even for a topic you feel should be easy - every page that ends up being in the final result, you have written at least 3x. The editing process alone…
